Abuout grid target

I am developing a grid-based combat game and encountering an issue with target selection. When creating single-target skills, I set the grid as the target and set the effect range to 0, allowing for normal attacks on enemies on the grid. However, a problem arises where the grid itself remains in the target list. This causes issues when determining factors such as backstab damage, as the grid always serves as the starting object in the skill's condition checks. Therefore, I would like to exclude the grid target from the skill animation schematic and only consider and calculate against enemies within range 0. How can I achieve this? Additional information: Why am I not using enemies as the target selection template? Using the grid as the target provides players with greater freedom and a smoother gameplay experience. For example, if enemies were used as the target template and a skill with a range of 1 is used, if the enemy is not within range, the skill becomes unavailable and the range is not displayed, which is far less effective than using the grid as the target . Your prompt reply would be greatly appreciated!
